I agree with you that there are three (maybe four) actions that are considered wrong across all cultures: stealing, lying, murder, and maybe rape. However, this is extremely general, as each culture (and person!) can have different definitions of what murder, for example, entails. Is killing someone in self-defense murder? There are also instances when it would seem permissible (itwillend's proclamation notwithstanding) to lie or steal, but perhaps these are simply wrapped up in a more complex or detailed definition of those things.Morality is concerned with the normative behaviours which all people, regardless of race of nationality consider improper because they are harmful to other sentient beings (beings that have some sort of sense of personal value, the capacity to suffer, the ability to have long term self interest...)
There are also instances of large blocks of people believing a certain action is immoral, such as homosexual acts or depicting Muhammed, and other blocks don't.
So, while I do believe that we have similar underlying tendencies in morality, I don't believe that it is as uniform as your statement suggests.
...or that evolution has ingrained them into us, and that societal culture (and pressure) reinforces them.The fact that these tend to be the same across all cultures suggests very strongly that they are not matters of opinion but of principle.
Ah, but there is an underlying assumption there. Is it a fact, in the same way that being punched in the face is unpleasant is a fact, that human beings are required to make sure that other human beings can live a decent life?Humans (and other sentient beings) don't like to be punched in the face, because it hurts. If it happened every day, it could really interfere with your ability to live a decent life. That's not my opinion, that's fact, which is, among other facts, the foundation for moral principles.
Perhaps the answer isn't to lower the standards of objectivity, but to realize that objectivity cannot be fully met?MSizer said:But it's not arbitrary. I agree that there's no celestial 3rd party to make an perfectly unbiased judgement, but the principles remain objective nonetheless. Even if we did have a third party to act as lawgiver, those laws would not be objective either. You're calling for a standard of objectivity that is unachievable. The standard I propose eliminates cultural or personal preference
